How to add nofollow to this script, and add "url" before links

Hi,

This is a helper script which makes opening url in new window possible. I will like to add nofollow tag to the links this script opens.

Also, i will like to add www .yoursite.com/redirect.php before the link this script opens. Like this : www .yoursite.com/redirect.php?url=www .yoursite.com

Here is the script :

// ------------------------------------------------------------------------
 
/**
* Anchor Link - Pop-up version
*
* Creates an anchor based on the local URL. The link
* opens a new window based on the attributes specified.
*
* @access    public
* @param    string    the URL
* @param    string    the link title
* @param    mixed    any attributes
* @return    string
*/
if ( ! function_exists('anchor_popup'))
{
    function anchor_popup($uri = '', $title = '', $attributes = FALSE)
    {
        $title = (string) $title;
 
        $site_url = ( ! preg_match('!^\w+://! i', $uri)) ? site_url($uri) : $uri;
 
        if ($title == '')
        {
            $title = $site_url;
        }
 
        if ($attributes === FALSE)
        {
            return "<a href='javascript:void(0);' onclick=\"window.open('".$site_url."', '_blank');\">".$title."</a>";
        }
 
        if ( ! is_array($attributes))
        {
            $attributes = array();
        }
 
        foreach (array('width' => '800', 'height' => '600', 'scrollbars' => 'yes', 'status' => 'yes', 'resizable' => 'yes', 'screenx' => '0', 'screeny' => '0', ) as $key => $val)
        {
            $atts[$key] = ( ! isset($attributes[$key])) ? $val : $attributes[$key];
            unset($attributes[$key]);
        }
 
        if ($attributes != '')
        {
            $attributes = _parse_attributes($attributes);
        }
 
        return "<a href='javascript:void(0);' onclick=\"window.open('".$site_url."', '_blank', '"._parse_attributes($atts, TRUE)."');\"$attributes>".$title."</a>";
    }
}

Code (markup):

Which in turn works with :

' . anchor_popup('gtellart/go/'.$l->linkID, $l->link_title) . '

Code (markup):

I will appreciate the help.

Thanks.
